Specification of Letters Patent.

Application filed July 9, 1918. Serial No. 244,025.

To all whom it may concern: 1

Be it known that I, STANTON F. BAKER, a citizen of the United States,residing at Reydel, in the county of Jefferson, State of Arkansas, haveinvented a new and useful Cap for Filling-Openings of Automobile-Radiators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the'same.

This invention relates to an improved cap or cover adapted for use inconnection with filling openings of automobile radiators, preferably ofthe Ford type.

Heretofore it has been found difficult to ascertain when the water inthe radiator is excessively warm or hot. Furthermore when the radiatoris hot, it is very annoying to unscrew the old style hot cap.

The present invention aims to avoid these disadvantages by providing aperforated cap, so that when the automobile is stopped, and in case thewater is hot, the'steam will percolate through the perforations, therebyindicating or notifying the necessity of refilling the radiator with afresh supply of cold water.

The invention further aims togprovide a hinged cap, whereby the cap maybe easily swung open, to avoid unscrewing.

The invention further aims to construct one end of one of the hingedmembers in a catch to engage a depression in the exterior of the flangedwall of the filling opening, to hold the cap closed. The inventionfurther aims to construct one of the hinge members in the form of aspring which is normally substantially straight when the cap is open, soas to exert constant pressure on the cap to hold it tight when closed.

The invention further aims to provide a cap, which may be applied to aradiator filli i; ing opening at the time of constructing the radiatoror may be applied to the filling openings of radiators now in use.

The invention further aims to provide means for holdin a brasscomposition or ether suitable was er between the cap and the flange ofthe filling opening.

Theinvention comprises further features and combination of parts ashereinafter set forth shown in the drawings and claimed.

In practical fields the details of construction may necessitatealterations falling within the scope of what is claimed.

In the drawings Figure 1 is a view in front elevation of an automobileradiator, showing the cap as applied to the filling opening.

Fig. 2 is a vertical sectional view through the filling opening on line2'-2 of 1.

Fig. 3 is a plan-view of Fig. 2.

Fig. 4 is a view in side elevation of a filling opening showing amodified form of cap.

Fig. 5 isa plan View of Fig. 4.

Fig. 6 is a sectional view on line 6-6 of Fig. 5.

Referring more especially to the drawings 1 designates a portion of aradiator having the usual filling opening 2 provided with a marginalflange 3, the inner circumference of which near the upper end isprovided with a ledge or rib 4, which is annular. Mounted upon the upperend of the flange of the filling opening is a cap 5, provided with adownwardly extending extension annular flange 6, between which and theledge 4 any suitable washer 7 constructed of any suitable material,preferably brass composition is interposed, in order to provide a tightjoint between the cap and the ledge. By means of the hinge connection8., the cap is hingedly mounted on the flange of the filling opening.One member of this hinge as at 9 is integrally carried by the flange ofthe filling opening, while the other member 10 is in the form of anelongated spring strip, which is riveted or otherwise fastened to thecap. This spring strip extends entirely across the upper surface of thecap, and has its extremity bent to form a lug 12 to engage a suitabledepression 13 in the front part of the upper end portion of the flange 3of the filling opening, to hold the cap closed. The extremity 14 beyondthe lug 12 is designed to be engaged by the finger, so as to disengagethe lug from the depression, when it is "desired to open the cap. Thespring strip when the cap is opened tends to become substantiallystraightened at the point indicated by the numeral 15, so that when thecap is closed a constant pressure on the washer or gasket 7 is exert"ed, to insure a tight joint. This joint is maintained materially sincethe cap as indicated at 16 near the marginal edge of the cap is spacedfrom the upper edge of the Patented Got. 115, 1918.

ind

.ring bushing 18, which is angular in cross section. This bushing isthreaded intothe usual flan'ge 3 of.. the filling opening. In

-this,method of construction, it is obvious that the cap may be appliedto flanged filling openings'of radiators now in use, while in Figs. 1, 2ahdBi-the cap is especially designed tobeiimstructed at the time ofconstructing' the radiator and its filling opening. In Figs. 4, 5 and 6the annular ledge 4 which is similar to the ledge 41in Fig. 2, iscarried by the bushing 18, so that the gasket or washer may fit betweenthe ledge and the extension flange'6. The cap in Fig. 6 is also spacedas at 16 from the'upper face of the bushing. The cap in Fig. 6 also hasperforations, and the spring strip 10 of the hinge 8 performs the samefunctions as the spring strip 10 of the hinge 8 in Fig. 2.

The invention having been set forth what is claimed as new and usefulis:

1. The combination with a flanged filling opening, of a cap engaging theflange of the filling opening, a hinge hingedly connecting the ca to theflange, one member of the hinge eing in the form of a spring stripextending across the top of the cap and-being connected thereto andhaving its end opposite the hinge terminating in a latchinglug,

ing connected thereto and having its end op'-' posite the hingeterminating in a latching lug, means on the flange of the fillin openingto receive said latching lug, an means to afl'ord a gasket. tight jointfor the cap, said cap having perforations. Y

3. The comblnation with a flanged filling opening, of a closure for saidflanged filling opening, said. closure comprising a bushing detachablyengaging said flange of the opening and a cap having perforations, ahinge connecting the cap to the bushing, one member of the hinge beingin the form of a spring strip extending across the top of the cap andbeing secured thereto and having itsend opposite the hinge terminatingin a latching lug, the flange of the filling opening having a depressionto receive said lug, a gasket tight joint between the bushing and thecap, said spring strip having means to exert constant pressure on thegasket tight joint.

In testimony whereof I have. signed my name to this specification in thepresence of twosubscribing witnesses.
